摘要： A device for withdrawal of a fixed volume of powdered, liquid or gaseous material from a withdrawal zone and for conditioning the withdrawn materials for the purpose of analysis which comprises a retractable cylindrical probe in which there is provided a cavity of known capacity, a retractable sleeve coaxially disposed over the probe for permitting or preventing access to the cavity, a substantially closed chamber in which the probe and sleeve are disposed for reciprocal movement into and out of the withdrawal zone, whereby the probe and sleeve may be extended from the chamber into the withdrawal zone, the sleeve may be retracted to fill the cavity, the sleeve may be extended to seal the cavity, the probe and sleeve may be retracted from the withdrawal zone back into the closed chamber, and finally, the sleeve may again be retracted to permit conditioning of the withdrawn material.

摘要： Process of continuously separating electrically charged, solid pulverulent materials in the form of a suspension in an electrophoresis and electroosmosis cell, characterized in that a fraction of the catholyte is drained off, that a portion thereof is treated with an acid, preferably gaseous, agent, that the treated portion is re-introduced into the cathode compartment, whereas the other part of the drained-off fraction is eliminated.The acid treatment is effected during continous pH measurements on the drained-off fraction of the catholyte.
摘要翻译：在电泳和电渗细胞中以悬浮液的形式连续分离带电荷的固体粉状材料的方法，其特征在于将一部分阴极电解液排出，其一部分用酸，优选气态的试剂处理，将处理的部分重新引入阴极室，而排出的部分的另一部分被消除。在对阴极电解液的排出部分的连续pH测量期间进行酸处理。
